The present invention relates to a vacuum pump and, more specifically, to a vacuum pump that is designed to change the direction of an intake port formed on a side wall of a housing, according to necessity. The vacuum pump includes: a housing; an ejector part embedded in the housing; and a pressing means provided on the outside of the housing. Particularly, the housing includes two or more parts, including a main part that has the intake port, which are disposed in a line, wherein a stopping member is formed along a contact surface there between. This structure enables the main part to rotate, and thus the direction of the intake port can be changed.

The present invention relates to an ejector assembly and a vacuum pump, the ejector assembly including a typical cylindrical vacuum ejector and a support part. The support part includes a first support having a supply line extending outwards from a hole in which a first end of the ejector is mounted, and a second support having a discharge line extending outwards from a hole in which a second end of the ejector is mounted. Further, the first and second supports facing each other are configured such that the outer circumferential surfaces thereof are in contact with the inner circumferential surface of a pipe member so as to form a space between the first and second supports, the space communicating with through holes. In the vacuum pump using the ejector assembly, the pipe member is a housing, and the space is a vacuum chamber formed in the housing.

The present invention relates to an ejector assembly and a vacuum pump, the ejector assembly comprising a typical cylindrical vacuum ejector and a support part for mounting opposite end portions thereof. Herein, the support part includes a first support having a supply line extending outwards from a hole on which a supply-side end portion of the ejector is mounted, and a second support having a discharge line extending outwards from a hole on which a discharge-side end portion of the ejector is mounted. Further, the first and second supports facing each other are designed such that the outer peripheral surfaces thereof make contact with the inner wall of a separately provided pipe member to form a space, communicating with the through hole, between both the supports. In the vacuum pump using the ejector assembly, the pipe member is a housing, and the space is a vacuum chamber formed in the housing.

The present invention relates to a check-valve assembly appropriately used in a vacuum system. The check-valve assembly of the present invention comprises a body having a plurality of through-holes formed therein while having different space characteristics. As a valve member rotates with a shaft fixed to the body, intake holes of the valve member selectively communicate with the through-holes. Accordingly, the check-valve assembly of the present invention can advantageously, properly, and promptly take action in accordance with a vacuum characteristic required on site.
Disclosed is a suctioning device. The present invention comprises: a sensor portion for measuring the state of breathing of a patient; a tube portion which is moved into the bronchial tube of the patient to aspirate impurities produced in the bronchial tube of the patient, when a measurement value measured by the sensor portion exceeds a specific reference value; and a control portion for controlling the driving of the tube portion on the basis of the measurement value measured by the sensor portion. According to the present invention, provided is the suctioning device which is automatically driven by directly determining whether impurities have been produced inside the bronchial tube of the patient.
